Hey Raven,

In order to install a wood floor properly over the Elastilon underlayment the instructions should be followed carefully and proper expansion break is a must for big rooms.

If you were to install the 50ft section going with the long length of the floor boards and not the width, you can go 50ft without adding a transition break.

When dealing with a 5” wide plank I like to put transitions in all doorways. This will allow extra room for the floor to expand. In any case the instructions should be followed. The following paragraph is from the Elastilon installation instructions:

"Expansion joints will also need to be installed in doorways, long hallways, and larger areas more than 33 ft (10 m) in length following the direction of the small width (eg. 3.5" width) of the floor boards. Additional Expansion joints are NOT necessary in the direction of the long length of the floor boards (and expanses longer than 33 ft are permitted). A small amount of white carpenters glue (PVA) must be applied to all adjoining ends (small ends of the boards).

I hope this helps. If you need more instruction, just let us know. Thanks for your inquiry!


I am using the Elastilon method but have one part of my house that incorporates two rooms and a hallway, where my flooring will be running about 50 feet "longs ways". I read in either the Bellawood or Elastilon installation instructions, that you shouldn't run more than 33 linear feet of flooring "long-ways" without a transition. Is this a hard and fast rule? I don't have a good place for a transition and would like the wood floor to flow from one room to the next without changing the direction. Using 3/4 x 5" Brazilian Cherry. Thanks for any ideas.

Thanks alot for this very informative post! Will try this out soon. I've tried different ways of installing over concrete slabs and I'm still experimenting to this day which is the best one.

The flooring industry always needs advice. I'm in a different area of flooring and when new technology and processes come out we need info like these blogs to help us navigate. Thanks Lumber Liquidators for keeping us up to speed. Very clean instructions.
